Abstract
Neuroendocrine tumours (NETs) originating from extrahepatic bile duct are an extremely rare entity. They are typically slow growing tumours with malignant potential. Commonly presenting as obstructive jaundice, preoperative clinico-radiologic differentiation between extrahepatic biliary tract neuroendocrine tumours and cholangiocarcinoma is difficult and the final diagnosis is usually established after surgical histopathology and immunohistochemistry examination. R0 resection offers the only curative option with good long-term outcomes for well-differentiated NETs (grade1, grade2, and grade3) while the aggressive poorly differentiated neuroendocrine carcinoma (NEC) needs multimodality approach. We present our experience of management of four cases including three cases of grade II NET and one case of NEC undergoing surgical resection at a single centre with a short review of available literature.

Abstract
BACKGROUND The main purpose of this study is to analyze the clinicopathological features and prognosis factors of bile duct and ampullary neuroendocrine neoplasms (NENs). METHODS The relevant data were collected from the SEER database from 1975 to 2016. The Kaplan-Meier curve and Cox model were used for survival analysis. The nomogram was drawn to predict the survival rate. The calibration, discrimination and clinical utility of the nomogram were evaluated by calibration curve, the concordance index (C-index) and decision curve analysis (DCA). RESULTS A total of 340 cases were included in our research. According to Kaplan-Meier analysis, 1-year, 3-year and 5-year of overall survival (OS) were 77.3%, 61.9% and 58.4%, while 1-year, 3-year and 5-year of the disease-specific survival (DSS) were 82.7%, 69.3% and 66.9%, respectively. The multivariable analysis results showed that age, histological grade, SEER stage and surgery were independent predictors for either OS or DSS. The calibration curve and the C-index value indicated that the nomogram was well calibrated and had good discrimination. DCA showed that the model had ideal net benefits. CONCLUSIONS The age, histological grade, SEER stage and surgery were identified as independent prognostic variables for OS and DSS. After verification, nomogram has good predictive ability and clinical application value.

Abstract
Background Neuroendocrine tumors (NETs) arise from neuroendocrine cells and are extremely rare in the biliary tract. Currently, there are no guidelines for the diagnosis and treatment of biliary NETs. We presented a case with NETs G1 of the hilar bile duct and the challenges for her treatment. Case presentation A 24-year-old woman was presented to our department with painless jaundice and pruritus, and the preoperative diagnosis was Bismuth type II hilar cholangiocarcinoma. She underwent Roux-en-Y hepaticojejunostomy with excision of the extrahepatic biliary tree and radical lymphadenectomy. Unexpectedly, postoperative pathological and immunohistochemical examination indicated a perihilar bile duct NETs G1 with the microscopic invasion of the resected right hepatic duct. Then the patient received 3 cycles of adjuvant chemotherapy (Gemcitabine and tegafur-gimeracil-oteracil potassium capsule). At present, this patient has been following up for 24 months without recurrence or disease progression. Conclusion We know little of biliary NETs because of its rarity. There are currently no guidelines for the diagnosis and treatment of biliary NETs. We reported a case of perihilar bile duct NETs G1 with R1 resection, as far as we know this is the first report. More information about biliary NETs should be registered.

Abstract
Background For this study, we explored the prognostic profiles of biliary neuroendocrine neoplasms (NENs) patients and identified factors related to prognosis. Further, we developed and validated an effective nomogram to predict the overall survival (OS) of individual patients with biliary NENs. Methods We included a total of 446 biliary NENs patients from the SEER database. We used Kaplan-Meier curves to determine survival time. We employed univariate and multivariate Cox analyses to estimate hazard ratios to identify prognostic factors. We constructed a predictive nomogram based on the results of the multivariate analyses. In addition, we included 28 biliary NENs cases from our center as an external validation cohort. Results The median survival time of biliary NENs from the SEER database was 31 months, and the value of gallbladder NENs (23 months) was significantly shorter than that of the bile duct (45 months) and ampulla of Vater (33.5 months, p=0.023). Multivariate Cox analyses indicated that age, tumor size, pathological classification, SEER stage, and surgery were independent variables associated with survival. The constructed prognostic nomogram demonstrated good calibration and discrimination C-index values of 0.783 and 0.795 in the training and validation dataset, respectively. Conclusion Age, tumor size, pathological classification, SEER stage, and surgery were predictors for the survival of biliary NENs. We developed a nomogram that could determine the 3-year and 5-year OS rates. Through validation of our central database, the novel nomogram is a useful tool for clinicians in estimating individual survival among biliary NENs patients.

Abstract
INTRODUCTION AND IMPORTANCE Biliary tree neuroendocrine tumors (NET) are rare, with 100 cases in the literature, and have an excellent prognosis. Although they are rarely diagnosed before surgery, complete surgical excision offers optimal treatment. CASE PRESENTATION We report a case of a 36-year-old female patient referred to the surgical team with obstructive jaundice for which she was investigated and found to have a common bile duct tumor showing proximal obstruction. Excision of the tumor with hepaticojejunostomy was done. Later on, the pathology report showed grade-1, well-differentiated neuroendocrine carcinoma, which was completely excised. No further intervention was provided to the patient. CLINICAL DISCUSSION Complete surgical resection with excision of the extrahepatic bile ducts and portal lymphadenectomy in addition to Roux-en-Y hepaticojejunostomy or even pancreaticoduodenectomy for distal CBD neuroendocrine tumors gives sufficient treatment in the majority of cases. No evidence of the advantage of chemo-radiotherapy as part of the treatment for this tumor. CONCLUSION Biliary tree neuroendocrine tumors are benign tumors, and it is usually difficult to ascertain the diagnosis preoperatively. However, complete surgical excision offers an optimal treatment with no evidence of chemotherapy or radiotherapy's role in the management.

Abstract
Common Bile Duct is extremely rare site for primary Neuroendocrine tumors. WHO classification categorized neuroendocrine neoplasms of digestive tract into three subtypes: well differentiated neuroendocrine tumor, poorly differentiated neuroendocrine carcinoma and mixed adenoneuroendocrine carcinoma. The etiology of developing NET in the bile duct tissues is unknown but it is related to chronic inflammation with subsequent metaplasia. Surgical resection is the mainstay of the treatment. Postoperative chemotherapy using cisplatin and etoposide showed promising results.
Introduction Neuroendocrine tumors (NET) of common bile duct are rare. There have been less than 100 cases reported worldwide. Presentation of case A 37-year-old female patient was referred to our center after six months of abdominal pain with no definite diagnosis. At initial presentation, she complained of increased abdominal pain, nausea, vomiting, oral intolerance to food and icteric sclera. Physical examination and laboratory tests were indicative of pancreatitis. At day four, she took retrograde cholangiopancreatography (ERCP) and a mid CBD stenosis or impacted stone was found. In order to locally investigate the lesion, Endoscopic Ultrasound (EUS) examination was performed which reported 16 × 12 mm isoechoic tumoral lesion at the middle of the CBD. In this regard we decided to perform ERCP-guided brushing biopsy of the lesion. The pathology report was highly suggestive for malignancy. She underwent resection of the mid portion of the CBD with Roux-en-Y hepaticojejunostomy, cholecystectomy and portahepatis lymph node dissection. The pathology report indicated that the CBD lesion was well-differentiated neuroendocrine tumor grade II. Discussion The exact etiology of developing NET in the bile duct tissues is not clear however cholelithiasis and congenital malformation of the biliary tract has been proposed to cause chronic inflammation with subsequent metaplasia which ultimately transforms into NET. Conclusion As there are very few cases of NETs of the CBD, no definite surgical or medical treatment is proposed. Currently, combination of radical surgical resection and lymph node dissection followed by chemotherapy is the treatment of choice.

Abstract
BACKGROUND Mixed adenoneuroendocrine carcinoma (MANEC) of the common bile duct (CBD) is very rare, with only 10 reported cases. Here, we report a case of MANEC of the distal bile duct (DBD) that was surgically resected under a diagnosis of cholangiocarcinoma (CCA). CASE PRESENTATION A 60-year-old male had epigastric pain and was admitted to our hospital for the treatment of a suspected CBD stone. Upon admission, laboratory findings revealed elevated hepatobiliary enzymes including serum aspartate aminotransferase, serum alanine aminotransferase, serum glutamyltransferase, and serum alkaline phosphatase. Both carcinoembryonic antigen and carbohydrate antigen 19-9 were negative. Computed tomography (CT) showed dilation of the CBD. Endoscopic retrograde cholangiopancreatography (ERCP) showed circumferential stenosis and a 5-mm elevated lesion in the DBD. Brush cytology showed atypical ductal cells, indicating adenocarcinoma (AC) of the DBD. Under a diagnosis of CCA of the DBD, a subtotal stomach-preserving pancreaticoduodenectomy was performed. Neither peritoneal dissemination nor lymph node metastasis was found. Microscopically, the lesion was seen to be composed of predominantly well-differentiated tubular AC in the superficial layer of the tumor, admixed with neuroendocrine carcinoma (NEC) in the deeper portion, indicating a diagnosis of MANEC of the DBD. After immunohistochemical staining, NEC components were positive for synaptophysin and CD56 and were for SSTR2, SSTR5, and mammalian target of rapamycin (mTOR). Three months postsurgery, postoperative adjuvant chemotherapy with S-1 was started. More than 3 years postsurgery, he is alive without recurrence. CONCLUSIONS MANEC is highly malignant, progresses rapidly, and has a poor prognosis. Preoperative diagnosis is difficult; therefore, identifying NEC components by immunohistochemical staining using resected specimens is important.

Abstract
Neuroendocrine neoplasm (NEN) comprises a group of tumors that exhibit neuroendocrine phenotypes. NEN is subclassified into neuroendocrine tumor (NET), neuroendocrine carcinoma (NEC) and mixed adenoendocrine carcinoma (MANEC), based on histopathological parameters. NEN in the extrahepatic biliary tract (EHBT) is uncommon. Little is known about its clinicopathological features and prognostic indicators. The present study presented a case of MANEC in the distal common bile duct (CBD) and reviewed previous cases of NENs in the EHBT to characterize the clinical settings of this disease entity and to identify influencing factors of survival outcomes. A 64-year-old Chinese woman presented with abdominal pain and jaundice. Imaging studies demonstrated malignant stenosis in the distal CBD. Bile duct brush cytology revealed small clusters of atypical cells. Following an initial diagnosis of distal cholangiocarcinoma (CCA), the patient underwent pancreaticoduodenectomy. Histological analysis combined with immunohistochemical investigation of the resected specimen revealed a collision tumor that was composed of poorly differentiated adenocarcinoma and NEC. Each histological component accounted for >30% of the tumor. The definitive diagnosis was a MANEC in the distal CBD. Multiple intrahepatic and pulmonary metastases were observed postoperatively over 8 months. The patient succumbed to the disease 12 months after surgery. In conclusion, NEN occurs infrequently in the EHBT, with NET being the predominant type. NEN in the EHBT is extremely challenging to diagnose preoperatively due to its tendency to mimic CCA. Patients with NEN in the EHBT exhibited extremely distinct oncology outcomes according to pathological types. Additionally, old age (>60 years) and the presence of tumor recurrence were associated with decreased survival of patients with NEN.

Abstract
Background The concept of mixed adenoneuroendocrine carcinoma (MANEC) was introduced in the 2010 World Health Organization classification of digestive neuroendocrine neoplasms. Bile duct invasion by MANEC is exceptionally rare. We herein report a case of MANEC with invasion of multiple bile ducts. Case presentation: A 60-year-old man presented with a 7-day history of upper abdominal pain, and a mass in the cystic duct was suspected based on computed tomography findings. The patient underwent resection of the extrahepatic bile ducts with concomitant radical lymphadenectomy and Roux-en-Y cholangiojejunostomy. Large cell neuroendocrine carcinoma was detected in a component of the resected tumor. According to the pathological and immunohistochemical features of the tumor, the final histopathological diagnosis was a biliary MANEC, tumor stage T2N0M1 (Stage IIIC). The patient recovered uneventfully and was discharged from the hospital 10 days after surgery. Conclusions We have described a rare case of extrahepatic MANEC invading multiple bile ducts, with particular emphasis on the physician’s awareness of MANEC and its optimal treatment. MANEC arising from extrahepatic bile ducts is rare, and surgical resection is the most effective treatment method.

Abstract
The biological behavior of neuroendocrine tumors (NETs) is heterogeneous and differs from that of cholangiocarcinoma, which is the most common malignant tumor of the biliary tree. However, the preoperative diagnosis of NET in the biliary tree is extremely difficult and to our knowledge, diagnosis by brush cytology has not previously been reported. Herein, we first reported a case of biliary NET preoperatively diagnosed by brush cytology in a 33-year-old female patient. Imaging study revealed a 2.6-cm mass in the common hepatic duct. The brush cytology was characterized by loosely cohesive plasmacytoid tumor cells and scattered clusters of thin vascular septa. The tumor cells showed abundant cytoplasm and severe nuclear size variation but mitosis was not observed. Immunohistochemical staining of the cell block (CB) showed strong positivity for both synaptophysin and chromogranin A and a Ki-67 labeling index of 3.5%. The surgically resected bile duct mass was pathologically confirmed as NET, G2 with lymphovascular and perineural invasion of the tumor cells. The patient showed no evidence of tumor recurrence 10 months after operation without adjuvant chemotherapy. Suspicion of this rare tumor and immunohistochemical staining of the CB are important for the preoperative diagnosis of NET in the biliary tree.

Abstract
We report a rare case of neuroendocrine tumor (NET) in the common bile duct (CBD). The patient is a 56-year-old female who presented to our department with symptoms of fever but without jaundice. A preoperative examination showed a tumor in the CBD. The tumor volume was almost 5.5 × 4.5 × 4 cm3, which is the biggest NET in the CBD reported on PubMed. The imaging results (computed tomography [CT] and magnetic resonance imaging [MRI]) were not consistent with CBD adenocarcinoma. The tumor appeared to oppress the growth of the CBD rather than originate in the bile duct wall; combined with the low blood bilirubin index and lack of jaundice symptoms, the preoperative diagnosis was not clear. We performed a radical resection of the cholangiocarcinoma. The patient recovered well before going home. The pathology was NET (Grade 2). The patient showed no recurrence to date, without intravenous chemotherapy (8 months).

Abstract
Neuroendocrine tumors (NETs) of the extrahepatic bile duct are extremely rare and reported infrequently in the literature. These tumors are difficult to diagnose preoperatively, and the prognosis is variable, often determined by extent of disease, tumor grade and resectability. This case report presents a 45-year-old male with history of biliary obstruction relieved by endobiliary stents with common hepatic duct stricture just above the cystic duct, thought to be a Klatskin’s cholangiocarcinoma. Final pathological examination was consistent with primary extrahepatic NET.
